To all whom, it may concern:

Be it known that I, HENRI PAUL illARTIN, i a citizen of the Republic ofFrance, residing at Paris, France, have invented a new and usefulImprovement 111 or Relating to Cvlinders for Internal-Combustion En'ines and the Like, which improvement is fully set fort-h in thefollowing specification.

This invention has for its; object a novel means of attaching thecylindenhcad ol internal-combustion engines and the like to thecylinder, such means consisting in screwing one end of it screw-threadedring into the upper portion of the cylinder and the other into' thelower portion of the evlinder-hezul.

This novel arrangement allows the bolts and i nuts now in use to bedispensed with and allows a. perfect olnt between the cylinderhead, thecylin er, and its jacket to he ol)-' tained.

In the annexed drawing, a is the cylinderhezi'd; b, the-cylinder; c, thejacket; 61, the screw-threaded ring or sleeve.

' As will be-seen the jacket 0 is squeezed between the lower face of thec finder-head and the upper-face of the cyinder. The joint thus 0 tainedis perfectly tight" This 5 is a very strong attucl'uuent and one, moreover, which allows the cylinder-head to be easily '(01'i1OV0(l.

Having now particularly described and 1 ascertained the nature ol' mysaid invention and in what manner the same is to be per- 3 formed, Ideclare that what I claim is- 1. The combinationv with the cylinder andits head having- :rlined apertures, one being i threaded, of a ringhaving a reduced threaded portion engaging the threaded aperture 1 toclamp the parts together. i 2. The coinoiniition, with the cylinder andits head having z'diued threaded apertures, 01 jacket having e flangelocated between the rylii'ider and head, and a ring having a reducedthreaded portion engaging the threevded apertures to clamp the partstogather. l In testimony whereof I have signed this specification in thepresence of two subscribl l l ing Witnesses.
